it will float
The density of an object is its mass divided by its volume. If that is less than the density of water, it will float; if greater it will sink
An object will float on water if it has less density than the water. Or than any other liquid on which it is supposed to float.
Normally the water - to float and object has to displace a volume of water equal to its mass. If its density is greater than that of water, the maximum mass of water it can displace is its own volume which, as the water is less dense that it, will have less mass than the object and it will sink. However, for small light objects the surface tension of water comes into play - it is possible to float a steel sewing needle (with a density greater than water) on water by gently dropping a clean needle on its side onto the water surface so that it does not break the surface tension. With a needle floating, adding a few drops of washing up liquid to the surface reduces the surface tension and the needle will then sink.
There are two ways to make an object with a density greater than water float on it: 1) reduce its density, for example by hollowing it out or adding further structures with a density [much] less than that of water so that it can displace a volume of water equal to its own weight and still have some of its structure above the surface of the water; or 2) Use the surface tension of water so that the object floats - dropping a steel sewing needle on its side very gently onto water will prevent it breaking the surface tension of the water and it will float, until such time as the surface tension is broken, eg by adding a few drops of washing up liquid or agitating the surface, when the needle will sink. (The needle needs to be clean.)
At room temperature, the density of sodium is slightly less than that of water and it will, briefly, float (briefly, because it will be rapidly reacting with the water, and may in fact be on fire at the time).
It floats
An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.An object will float - on water for example - if its density is less than the density of water.

-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.

The weight does not determine if an object will float in water. If an object has a DENSITY that is more than the density of water then it will sink, if it's density is less than the density of water it will float.
If the object's original density is less than water (sponge, for example) - the density will increase. If the object's original density is greater than that of water (though I cannot think of anything that fits that category that is porous enough to absorb water), the density will decrease.
The density of an object is constant, therefore, no rock can have less density in water.
Some objects will float on water as the density of the object is less than that of water. Conversely, if an object is more dense than the density of water, then it will sink.
An object will float in water if it has LESS density than the water.
ok so when the object hits the water, the water pushes up with the same amount of force (boyancy ) but if the object has a greater density than the water then the object has more force pushing down on the water and then it sinks. more dense=sink, less dense =float
We both know it floats
